PSL is a standard library for PHP inspired by Hack's HSL, providing consistent, well-typed APIs for collections, async, I/O, cryptography, validation, and terminal UI. It replaces PHP's inconsistent built-in functions with safer, async-ready alternatives that fail predictably.

Use cases

• validate and coerce untrusted input with type combinators
• run concurrent tasks with structured concurrency in PHP
• work with collections using type-safe functional operations
• hash passwords and generate secure random values
• build terminal UIs with ANSI support
• handle multibyte strings and grapheme clusters correctly
• perform non-blocking TCP and network I/O

When to choose

• you want a consistent, type-safe alternative to PHP's scattered built-in functions
• you need structured async concurrency in PHP without promise/callback complexity
• you're building PHP 8.4+ applications that benefit from strict typing and predictable errors

When to avoid

• you must support PHP versions older than 8.4
• you're maintaining a legacy codebase deeply tied to native PHP functions
• you only need a tiny utility and don't want a full standard library dependency
